22 The inflammatory response is a primary mechanism in the pathogenesis of ventilator-induced 23 lung injury. Autophagy is an essential, homeostatic process by which cells break down their own 24 components. We explored the role of autophagy in the mechanisms of mechanical ventilation25 induced lung inflammatory injury. Mice were subjected to low (7 ml/kg) or high (28 ml/kg) tidal 26 volume ven...

Numerous experimental studies demonstrate key aspects of mechanical ventilation which initiate or exacerbate acute lung injury, characterized by proteinaceous edema, inflammation, and hemorrhage. The great majority these investigations into Ventilator-Induced Lung Injury (VILI) have focused on the characteristics directly regulated clinician, including individual tidal cycle-tidal volume, inspi...

Excessive stretch of the cervical facet capsular ligament induces persistent pain and spinal plasticity at later time points. Yet, it is not known when such spinal modifications are initiated following this painful injury. This study investigates the development of hyperalgesia and neuronal hyperexcitability in the spinal cord after a facet joint injury. Behavioral sensitivity was measured in a...

The main supportive therapy in acute respiratory distress syndrome patients is mechanical ventilation. As with any therapy, mechanical ventilation has side-effects, and may induce lung injury (ventilator-induced lung injury (VILI)/ventilator-associated lung injury). The mechanical factors responsible for VILI are thought to be related to tidal recruitment/derecruitment of previously collapsed a...

OBJECTIVE The role of airway pressure release ventilation in the management of early smoke inhalation injury has not been studied. We compared the effects of airway pressure release ventilation and conventional mechanical ventilation on oxygenation in a porcine model of acute respiratory distress syndrome induced by wood smoke inhalation. DESIGN Prospective animal study. SETTING Government ...

BACKGROUND Mechanical ventilation causes ventilator-induced lung injury in animals and humans. Mitogen-activated protein kinases have been implicated in ventilator-induced lung injury though their functional significance remains incomplete. We characterize the role of p38 mitogen-activated protein kinase/mitogen activated protein kinase kinase-3 and c-Jun-NH(2)-terminal kinase-1 in ventilator-i...

PURPOSE OF REVIEW Patients who experience severe trauma are at increased risk for the development of acute lung injury and acute respiratory distress syndrome. The management strategies used to treat respiratory failure in this patient population should be comprehensive. Current trends in the management of acute lung injury and acute respiratory distress syndrome consist of maintaining acceptab...

objectives: to compare the results of early versus late tracheostomy in trauma patients admitted to intensive care unit (icu). methods: this was case control study being performed at a major trauma centre in shiraz, iran including 120 trauma patients admitted to icu during a 2-year period and underwent tracheostomy during their icu stay. the patients were categorized into two groups of the earl...

background: unexplained infertility is still a challenging issue as to its causes, appropriate management and treatment. evidence implicates early embryopathy or implantation failure as likely causes. objective: this study aims to investigate the effect of local endometrial injury on pregnancy rate in selected unexplained infertile patients. materials and methods: this was a randomized clinical...

We tested the ability of lithium (Li(+)) to block heat hyperalgesia, cold allodynia, mechanical allodynia and mechanical hyperalgesia in rats experimentally subjected to painful peripheral neuropathy. Chronic constrictive injury (CCI) to the sciatic nerve induced persistent hyperalgesia and allodynia. Intrathecal injection of Li(+) (2.5-40 micromol) into the region of lumbar enlargement dose-de...
